FIELD OF THE INVENTION

Certain embodiments of the invention relate to communication systems. More specifically, certain embodiments of the invention relate to providing content remotely via one or more IP multimedia residential gateways.

BACKGROUND OF THE INVENTION

Telecommunication technologies have evolved from analog to digital technologies, and continues to evolve from circuit switched to packet switched, from connection oriented packet switching to connectionless packet switching, and from narrow band application to broadband applications. The accompanied evolution in telecommunication technologies has significantly advanced operators' capability to offer broadband, IP-based multimedia services (IMS) ranging from entertainment and lifestyle applications such as mobile TV and mobile payment to professional services such as video conferencing and real-time data exchange.

IMS defines a standard framework for the deployment of next generation Web-based application services. IMS defines how these services connect and communicate with the underlying telecommunications network(s) and how they integrate with the network provider's back-end systems. IMS combines voice and data in one packet switched network such as, for example, the GPRS core network and the LTE core network, to offer network controlled multimedia services. Various Internet Protocols (IPs) such as the Session Initiation Protocol (SIP), the User Datagram Protocol (UDP), the Transmission Control Protocol (TCP) and Real-Time Transport Protocol (RTP) are widely utilized for delivery of various forms of multimedia applications over IP networks. SIP is an end-to-end application layer signaling protocol that is utilized to setup, modify, and teardown multimedia sessions such as audio/videoconferencing, interactive gaming, virtual reality, and call forwarding over IP networks. UDP and TCP are transport layer protocols that are used for data delivery over IP networks. TCP guarantees data delivery and integrity, however, UDP does not exclusively guarantee delivery of data. RTP is the Internet protocol which transmits real-time data such as audio and video data. RTP does not exclusively guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with the present invention as set forth in the remainder of the present application with reference to the drawings.

Each of the one or more of the plurality of communication devices that are communicatively coupled to the IP multimedia gateway may be local with respect to the IP multimedia gateway or may be remote with respect to the IP multimedia gateway. The IP multimedia gateway may be integrated in, for example, a set-top-box, a digital television or a video device such as a video projector. In addition, one or more of the plurality of communication devices may be integrated within the set-top-box, the digital television or the video device such as the video projector; and may be operable to display the content. Login access may be enabled for one or more of the communication devices for submission of the request and/or for requesting information about content that one or more other of the communication devices is operable to consume. Cooperation with one or more other IP multimedia gateways may enable one or more of the discovery of other IP multimedia gateways, the discovery of one or more communication devices and the communication of the content and/or of the information about the content, based on the received content sharing service profiles. In this manner, an IP multimedia gateway may provide content to a plurality of local and/or remote communication devices.

FIG. 1 is a diagram illustrating an exemplary communication system comprising an IP multimedia residential gateway that is operable to provide a content sharing service among local and remote communication devices, in accordance with an embodiment of the invention. Referring to FIG. 1, there is shown a communication system 100 comprising a plurality of IP multimedia residential gateways (IMRGs), of which IMRGs 112-114 are illustrated, broadband IP networks 120 comprising a plurality of core networks of which core networks 122-129 are shown, a plurality of communication devices 132 a˜132 e, 134 a˜134 c, 136 a˜136 e, and 138 a˜138 c, which may be referred to collectively herein as the communication devices 132, 134, 136 and 138, respectively, a plurality of access networks 142-146, and IP-based application servers 150, of which application servers 150 a-150 c are displayed.

The communication devices 132 a˜132 e may be referred to as local devices with respect to the IMRG 112 and the communication devices 134 a˜134 c, 136 a˜136 e, and 138 a˜138 c may be referred to as remote devices with respect to the IMRG 112. Similarly, the communication devices 136 a˜136 e may be referred to as local devices with respect to the IMRG 114 and the communication devices 132 a˜132 e, 134 a˜134 c, and 138 a˜138 c may be referred to as remote devices with respect to the IMRG 114. The communication devices 132, 134, 136 and 138 may be referred to as client devices with respect to the IMRGs 112 and/or 114.

In various embodiments of the invention, the IMRGs 112 and/or 114 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to communicate content to the local and/or remote communication devices. For example, content may be received and/or stored in the IMRGs 112 and/or 114 prior to distribution to one or more of the communication devices 132, 134, 136 and/or 138. The content may be received by the IMRGs 112 and/or 114 from a service manager network device, an Internet application server and/or a recording and/or playback device. Notwithstanding, the invention is not limited with regard to any specific source of content. A service manager network device may be referred to as a service manager.

The IMRGs 112 and/or 114 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to provide content sharing services to the communication devices 132, 134, 136 and/or 138. The IMRG content sharing services may enable a plurality of the communication devices to receive concurrently and/or at various delayed times, specified content via an IMRG. For example, IMRG content sharing services may enable one or more local and/or remote communication devices to receive content that is being consumed and/or is selected by another communication device. Moreover, IMRG content sharing services may enable one or more local and/or remote communication devices to receive information about which content is being consumed by and/or is selected by another communication device. For example, a user may be presently viewing video content such as a television program via an IMRG and the content may be distributed to another communication device via the IMRG and/or one or more other IMRGs. Alternatively, a communication device may be programmed to select and/or to receive content such as television content via an IMRG and a user may access the program from another communication device via the IMRG and/or one or more other IMRGs.

In an exemplary embodiment of the invention, a user of the communication device 132 d may request via the IMRG 112, content and/or information about content that another local or remote communication device is consuming. For example, the communication device 132 d may be operable to login to the IMRG 112 to see what content other local and/or remote devices are consuming and may request access to the content. Alternatively, a user of the communication device 132 d may invite one or more other communication devices to consume the same content being consumed by the communication device 132 d via the IMRG 112. In this manner, a plurality of communication devices may receive, for example, the same television program concurrently or at a delayed time. The IMRGs 112 and/or 114 may be operable to communicate a plurality of programs to one communication device such that a user may concurrently view their own choices of media in addition to media selected by a user of another communication device. For example, a display may be partitioned into a plurality of areas for concurrently viewing different streams of content. Audio for one of the areas may be selected by a user.

In various embodiments of the invention, a service manager may manage, control and/or may perform the content sharing services. The service manager may comprise one or more of the core networks 122-129, one or more of the IP-based application servers 150. The IMRG 112 and/or the IMRG 114 may perform content sharing services directed to the communication devices 132, 134, 136 and/or 138, under control and/or restrictions imposed by the service manager. The service manager may be operable to communicate content and/or may enable content sharing services for the communication devices 132, 134, 136 and/or 138 via the IMRGs 112 and/or 114.

The IMRGs 112 and/or 114 may be operable to receive content and/or control information from a service manager for distribution of the content to one or more of the plurality of the communication devices 132,134, 136 and/or 138. One or more of the plurality of communication devices 132, 134, 136 and/or 138 may be configured as a subscriber to the service manager. The service manager may configure and/or provision the IMRGs 112 and/or 114 utilizing one or more content sharing parameters. For example, the IMRGs may be configured with content sharing service permissions and/or subscriber and/or communication device content sharing profiles for enabling and/or controlling secure content sharing services among specified communication devices and/or among members of a group of communication devices. A communication device or subscriber profile may comprise information such as, for example, types of services and/or content that may be available to communication devices and/or may comprise access permissions for one or more communication devices.

A communication device and/or a subscriber profile may comprise information and/or configuration parameters associated with a specified communication device. The communication device and/or subscriber profiles may be utilized to enable content sharing services. For example, a profile for a specified communication device or a specified subscriber, may comprise parameters for user preferences, user permissions and/or a user service agreement profile that may be based on a service manager service agreement, for example. In this regard, a service agreement may indicate different classes of service to which a communication device or a user may subscribe. The service agreement and/or the classes of service may enable communication and/or sharing of content at appropriate data rates and/or at an appropriate quality of service for the specified subscriber and/or the communication device. Shared content may comprise, for example, streaming video and music, conversational voice, interactive gaming and/or 3D video. The communication devices 132, 134, 136 and/or 138 may also be configured for enabling and/or disabling secure content sharing. The IMRGs 112 and/or 114 may be operable to communicate information regarding the communication devices to the service manager. A service manager may be referred to as carrier or network operator equipment, for example.

An IMRG such as the IMRG 112 may comprise suitable logic, circuitry, interfaces and/or code that are operable to connect the communication devices 132 a-132 e to the broadband IP networks 120 for services of interest. A service may be described or represented by the service type and the service class. The type of a service refers to the type of information to be transferred, such as data, voice, text or radio for the service.

In addition, a service class for IMRG content sharing may be provided that may enable users to share television programs, video, music, voice, gaming and/or other content via an IMRG. The IMRG may provide content sharing services to local and/or remote communication devices where users may, for example, share content and/or may see which content other communication devices are consuming.

Specific requirements may be placed on access networks and core networks for each service type and/or class to ensure desired end-to-end QoS. The service requirements on access networks and core networks may comprise, for example, system timing, CODEC, transmission rates, power-saving mechanisms, security profiles and content types. The system timing may be utilized to synchronize communications for delivery of service. The CODEC may comprise G.711, G.729, G.723, MPEG-4, VC-1, and VP6, for example. The power-saving mechanisms may comprise various power levels, which may be utilized within certain time intervals, for service transmissions. The security profiles may comprise service security descriptions such as, for example, security configurations and policies. The security configuration of a service, for example, IMRG content sharing, may comprise protocols, credentials, and actions such as authentication actions. The content type of a service may specify what type of content that the service may comprise. The content type for a service may comprise, for example, Multipart Internet Mail Extensions (MIME) files, HTML pages, H.262, H.263, H.264/AVC video, G.711 voice, BV16, BV32 and DOCSIS Set-top Gateway (DSG) multimedia.

In various exemplary embodiments of the invention, the IMRG 112 may be operable to integrate local communication devices as well as remote communication devices to the broadband IP networks 120. Communication devices such as the communication devices 132 a-132 e that may access the IMRG 112 via device-dependent interfaces are referred to as local communication devices for the IMRG 112. A device-dependent interface may generally represent the PHY and MAC functionality of a particular access technology such as, for example, Ethernet, Wi-Fi, Bluetooth, cordless, and/or Femtocell. Communication devices such as the communication devices 132 a-132 e that may access the IMRG 112 via device-independent interfaces such as the broadband IP networks 120 are referred to as remote communication devices for the IMRG 112.

In various exemplary embodiments of the invention, for example, when communication devices are operable to share content with other local and/or remote communication devices, the IMRG 112 may be operable to perform automatic device and network discovery. In this regard, the IMRG 112 may be operable to utilize proprietary methods and/or well-known networking protocols such as uPnP and DHCP, or a combination of both to perform search, in the background or transparently, for attached communication devices and broadband IP networks. For example, the IMRG 112 may be operable to multicast a discovery message. The IMRG 112 may discover or identify attached devices and/or networks from responses received to the discovery message. In this regard, the IMRG 112 may be operable to retrieve or determine, from the received responses, communication device capabilities for the discovered devices, and/or network capabilities for the discovered networks. The communication device capabilities may comprise interface types, processing protocols, service types, service classes, service requirements and/or IMRG content sharing capabilities. The interface types for the identified device may comprise access interface types such as CDMA for GNSS, Multimedia over Coax Alliance (MoCa), WiFi, Ethernet, Femtocell, and/or cordless.

The service layer protocols may comprise secure protocols such as Secure Sockets Layer (SSL) and control protocols such as Spanning Tree Protocol (STP). The IP layer protocols may comprise IP signaling protocols such as SIP and H.323, and IP media transport protocols such as TCP, RTP, UDP, RTC, and RTCP. The link layer protocols may comprise technology-specific PHY and MAC layer protocols such as, for example, MoCA, WiFi, Ethernet, Femtocell, and/or cordless. With regard to IMRG content sharing capabilities, the communication devices may comprise content sharing resources and/or resource availability, content sharing permissions and/or restrictions and/or content sharing group information. The network capabilities may comprise interface types, processing protocols, service types, service classes and service requirements on network side. The interface types for the identified networks may comprise technology specific broadband IP connections such as DSL, Cable, FTTx, PLC and WiMAX. The protocols may comprise service layer protocols such as SSL and STP, technology-independent IP layer protocols such as SIP, TCP, and technology-dependent IP layer protocols such as Base Station System GPRS Protocol (BSSGP).

In various exemplary embodiments of the invention, the IMRG 112 may be operable to register discovered or identified communication devices and networks into a local database 112 a. In this regard, the registered communication devices may comprise local communication devices such as the communication devices 132 a-132 e as well as remote communication devices such as the communication devices 134, 136 and/or 138. Information such as communication device capabilities and network capabilities may be stored in the local database 112 a to support various applications or features. For example, the stored communication device capabilities may be utilized to implement the IMRG content sharing feature. In this regard, the IMRG 112 may be configured by a service manager and/or by a user, for example, with various permissions for sharing content among communication devices. Communication devices may be associated in groups that may be given permissions to share content among group members. Permissions may vary among various groups and/or various group members with regard to which content may be shared and/or reported.

In various exemplary embodiments of the invention, the IMRG 112 may be operable to access local communication devices utilizing device-dependent interfaces. In this regard, the IMRG 112 may be operable to support link layer protocols for specific PHY and MAC functionality of a particular access technology. For example, in instanced where the IMRG 112 is signaled to access a Bluetooth enabled communication device such as the communication device 132 b, the IMRG 112 may be operable to communicate information with the communication device 132 b utilizing Bluetooth air interface protocols.

The IMRG 112 may be operable to provide one or more common IP protocol-based interfaces towards communication devices. In this regard, the IMRG 112 may be comprise a common IP layer communication device interface to enable communication utilizing a wide range of communication devices to, for example, a single common IP transport protocol and a single common IP signaling protocol. For example, the IMRG 112 may be operable to convert or configure different IP transport protocols utilized by the communication devices 132 a-132 e into the single IP common transport protocol such as RTP. Different IP signaling protocols running on the communication devices 132 a-132 e may be converted into the single common IP signaling protocol such as SIP.

The IMRG 112 may be operable to route and distribute information such as media, signaling and event packets among communication devices registered to the IMRG 112. In this regard, the IMRG 112 may be operable to track registration status for communication devices dynamically registered as local clients or remote clients (during roaming). The IMRG 112 may be configured to monitor and/or discover communication device capabilities and network capabilities to dynamically configure registered communication device based on communication device capabilities and network capabilities.

The IMRG 112 may be operable to control or manage system timing and power-saving mechanisms for registered communication devices. For example, the IMRG 112 may be operable to adjust system timing based on corresponding service requirements for service deployment provided by different broadband IP networks over corresponding communication devices. For example, the IMRG 112 may be operable to manage power consumption on communication devices based on corresponding communication device capabilities and network capabilities to receive content of services offered by one or more service managers through different broadband IP networks.

The IMRG 112 may be operable to support various broadband connections such as, for example, DSL, Cable, FTTx, PLC and WiMAX. In this regard, the IMRG 112 may be operable to communicate with different broadband IP networks utilizing technology-dependent access for network access.

For example, the IMRG 112 may be operable to convert a common IP media transport protocol such as RTP and a common IP signaling protocol such as SIP to different media transport and signaling protocols utilized by corresponding broadband IP networks.

The IMRG 112 may be operable to control or manage system timing and power-saving mechanisms for registered networks. For example, the IMRG 112 may be operable to adjust system timing based on corresponding service requirements for services provided by different broadband IP networks. For example, the IMRG 112 may be operable to control its own power levels and/or power consumption based on corresponding network capabilities to receive services from different broadband IP networks.

Although IP multimedia residential gateways (IMRGs) are illustrated in FIG. 1 for connecting communication devices through a common-protocol-based interface to broadband IP networks via a configurable interface, the invention is not so limited. Accordingly, other IP multimedia gateways for connecting communication devices through a common-protocol-based interface to broadband IP networks via a configurable interface may be supported without departing from the spirit and scope of various embodiments of the invention. The IP multimedia gateways may be located in a residential location and/or non-residential locations comprising, for example, a commercial building, an office, an office complex, an apartment building and/or a factory.

A communication device such as the communication device 132 a may comprise suitable logic, circuitry, interfaces and/or code that are operable to receive services from different broadband IP networks through the IMRG 112. In various exemplary embodiments of the invention, the communication device 132 a may be operable to utilize an access technology specific interface such as Bluetooth, LTE, WiFi and/or Ethernet to communicate with the IMRG 112 for services offered by different broadband IP networks.

In various embodiments of the invention, one or more of the IP-based application servers 150 may comprise service manager network equipment that may be operable to provide content, such as, television programming, video, music, voice and/or gaming content to the IMRGs 112 and/or 114 for distribution to the communication devices 132, 134, 136 and/or 138. For example, one or more of the IP-based application servers 150 may comprise service manager network equipment. Furthermore, one or more of the IP-based application servers 150 may function as a service manager “head-end,” which may provide multimedia services to the IMRGs 112 and/or 114 and/or to the communication devices 132, 134, 136 and/or 138. The multimedia services may comprise streaming and/or downloading of content such as television programming, film, gaming, video, and/or audio content for use in communication devices. The multimedia services may be delivered to communication devices via IMRGs such as the IMRGs 112 and/or 114. For example, the content may be delivered to the IMRG 112 via one or more of the broadband IP networks 120 and/or via other IMRGs such as the IMRG 114. The IMRGs 112 and/or 114 may be operable to distribute the shared content to one or more local communication devices and/or to one or more remote communication devices via the broadband IP networks 120 and/or via one or more other IMRGs. The service manager may be operable to control which communication devices 132, 134, 136 and/or 138 may have permission to receive the shared content. In addition, the service manager may be operable to bill communication device users and/or other entities, for access to the shared content and/or for access to information about the shared content. In various embodiments of the invention, an IMRG such as the IMRG 112 may receive content from an IP based application server 150 and may forward the content to another IMRG such as the IMRG 114 for distribution to one or more communication devices that are local to the IMRG 114, such as the communication device 136 b.

The communication devices 132, 134, 136 and 138 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to receive and/or display content communicated from IMRGs such as the IMRGs 112 and/or 114. The communication devices 132, 134, 136 and/or 138 may be operable to access and/or interact with local and/or remote IMRGs such as the IMRGs 112 and/or 114 to select content and/or to utilize IMRG content sharing services. In this regard, a first communication device may be operable to access a local or remote IMRG and may request content that may be currently consumed and/or selected by a second communication device. For example, the communication device 134 c may request content from the IMRG 112, which is being consumed by the communication device 132 b via the IMRG 112. In instances when permission is granted to the communication device 134 c for sharing the content, the IMRG 112 may stream the content to the communication device 134 c via the broadband networks 120.

Alternatively, a first communication device may be operable to invite a second local or remote communication device to “share” or receive content that is consumed and/or selected by the first communication device. The content may be delivered to the first and second device via an IMRG that is serving content to the first communication device. The communication devices 132, 134, 136 and/or 138 may be operable to access local and/or remote IMRGs 112 and/or 114 via the broadband IP networks 120. For example, the communication device 136 c, which may comprise a video client, may select and/or may be currently consuming a television program. The communication device 136 c may invite the communication device 132 e which may also comprise video capabilities, to share or receive the same content. In instances when the communication device 132 e may be configured with permission to share content being consumed or selected by the communication device 136 c, the IMRG 114 may communicate the content to the communication device 132 e via the broadband IP networks 120 and/or via the IMRG 112. The IMRG 114 may concurrently communicate the content to the communication device 136 c. Furthermore, a plurality of communication devices may request content and/or may be invited to share content from another communication device. The communication devices 132, 134, 136 and/or 138 may be operable to display a plurality of video streams concurrently and/or may enable users to select audio from one of the plurality of video streams.

In an exemplary operation, an IMRG such as the IMRG 112 may comprise a stand-alone device or may be embedded and/or integrated within another device. For example, an IMRG may be integrated within a set-top-box and/or a digital television and may be coupled to a video communication device. Furthermore, an IMRG may be installed in any suitable location such as residence or enterprise environment. For example, an IMRG may be located at a residential property where one or more users, such as a family may be served by the IMRG. Alternatively, an IMRG may be installed in a location where a plurality of residences or a community of users may be able to access the IMRG with communication devices that may operate as local communication devices with respect to the IMRG.

An IMRG such as the IMRG 112 may be operable to communicatively couple a plurality of communication devices to the broadband IP networks 120. Communication devices discovered by the IMRG 112 may be registered together with corresponding communication device capabilities into the local database 112 a to support applications such as content sharing services. The IMRG 112 may serve local communication devices such as the communication devices 132 a-132 e as well as remote communication devices such as the communication devices 134 a-134 c.
